Journal ArticleDOI
Phototrophic extracellular electron uptake is linked to carbon dioxide fixation in the bacterium Rhodopseudomonas palustris.
Michael S. Guzman,Karthikeyan Rengasamy,Michael M. Binkley,Clive Jones,Tahina Onina Ranaivoarisoa,Rajesh Singh,David A. Fike,J. Mark Meacham,Arpita Bose +8 more
TL;DR: This work shows that phototrophs can directly use solid-phase conductive substances for electron transfer, energy transduction, and CO2 fixation.
Journal ArticleDOI
Reduction of hexavalent chromium by the thermophilic methanogen Methanothermobacter thermautotrophicus
Rajesh Singh,Hailiang Dong,Deng Liu,Linduo Zhao,Amy R. Marts,Erik R. Farquhar,David L. Tierney,Catherine B. Almquist,Brandon R. Briggs +8 more
TL;DR: The ability of M. thermautotrophicus cells to reduce toxic Cr6+ to less toxic Cr3+ and its potential application in metal bioremediation, especially at high temperature subsurface radioactive waste disposal sites, where the temperature may reach ∼70°C is demonstrated.
Journal ArticleDOI
Towards sustainable bioplastic production using the photoautotrophic bacterium Rhodopseudomonas palustris TIE-1
TL;DR: This is the first study to systematically quantify the amount of PHB produced by a microbe via photoelectroautotrophy and photoferroautOTrophy, and suggests that the variations in PHB accumulation might be post-transcriptionally regulated.
Journal ArticleDOI
The Impact of Silicon on Photosynthetic and Biochemical Responses of Sugarcane under Different Soil Moisture Levels
Krishan K. Verma,Xi-Hui Liu,Wu Kaichao,Rajesh Singh,Qi-Qi Song,Mukesh Kumar Malviya,Xiu-Peng Song,Pratiksha Singh,Chhedi Lal Verma,Yang-Rui Li +9 more
TL;DR: In this article, the responses of sugarcane with silicon application to drought stress for photosynthetic and biochemical activities were investigated, and it was found that the silicon application improved the plant growth under water stress.
Journal ArticleDOI
Mitigating Climate Change for Sugarcane Improvement: Role of Silicon in Alleviating Abiotic Stresses
Krishan K. Verma,Pratiksha Singh,Xiu-Peng Song,Mukesh Kumar Malviya,Rajesh Singh,Gan-Lin Chen,S. Solomon,Yang-Rui Li +7 more
TL;DR: In this article, the use of silicon could stimulate plant growth and mitigate multiple stresses such as salinity, drought, heat, extreme temperature, metal toxicity and nutritional imbalance as well as the stress linked with changes in global climatic variables.
